Edges are not seamed but are instead cut using a hot cut fabric knife to prevent fraying.
For pack covering extension option: measure from top of shoulder up over the pack and back to the same height used for specifying back length without the pack. The difference will be the length of fabric tucked out, so side zips will work correctly either way.
Width: full 65″ width of fabric.
Weight: 8 to 10 ounces depending on size.
Also provide hat size or head circumference for the hood.
Optional: Ponchos can also be made from Fuzzy Stuff for softer drape and wicking inner surface, but weight is almost doubled.
